This invention relates to the preparation of N-(phosphonomethyl)glycine (“glyphosate”) from N-(phosphonomethyl)iminodiacetic acid (“PMIDA”), and more particularly to methods for control of the conversion of PMIDA, for the identification of reaction end points relating to PMIDA conversion and the preparation of glyphosate products having controlled PMIDA content.
摘要:
The invention relates to a device for producing CO2, N2 and/or SO2 from a sample for a quantitative analysis of the sample, comprising a reactor structure and metals acting in an oxidizing manner or metal oxides in the reactor. According to the invention, the reactor structure has at least two zones through which the sample can flow, which is to say a first zone with reactor metal and reservoir metal, or only reactor metal, and following the first zone, a second zone with reactor metal and reservoir metal, or only reservoir metal, wherein both metals can form oxides, and wherein the ratio of the reactor metal to the reservoir metal in the first zone is greater than in the second zone.

This invention provides a method for measuring glucose metabolism ability of a subject and a composition that is suitably used in the method. The method for measuring glucose metabolism ability of the present invention is as follows: a method for measuring glucose metabolism ability of a subject, using a composition for measuring glucose metabolism ability, the composition comprising, as an active ingredient, glucose labeled with at least one isotope of C, wherein the glucose is converted in the body into labeled carbon dioxide that is excreted in expired air, the method comprising steps (a) and (b) below: (a) administering the composition to the subject and collecting expired air; and (b) determining the ratio of labeled CO2 amount to unlabeled CO2 amount or the ratio of labeled CO2 amount to total CO2 amount.

A integrated circuit die includes a chemical sensor, a thermal sensor, and a humidity sensor formed therein. The chemical sensor, thermal sensor, and humidity sensor include electrodes formed in a passivation layer of the integrated circuit die. The integrated circuit die further includes transistors formed in a monocrystaline semiconductor layer.
摘要:
The present disclosure relates to a gas sensor, including: a gas collecting chamber including: (a) a nanoporous wall including alumina, on a portion of the gas collecting chamber in the near vicinity of the solid propellant fuel; a micro pump attached to the gas collecting chamber; and a gas analysis device connected to the gas collecting chamber. The gas analysis device measures both type and concentration of gases collected in the gas collecting chamber via the nanoporous wall, the gases measured being selected from the group consisting of CO, CO2, NO, N2O, NO2 and combinations thereof. The present disclosure also relates to a method of sensing propellant degradation in solid fuel and a method of using a gas collecting chamber to sense such degradation.
